LOG

Syntax #1:

LOG( x:Number )

Returns gives the logarithm[1] of x to base ten.

x must be > 0.

Example:

LOG(64)

returns the number 1.80618.

Revisions:

Syntax #2 (2.00+):

LOG( x:Number, b:Number )

Starting with 2.00, this function will accept an extra optional numeric parameter, b, returning the logarithm[1] of x to base b. If b is omitted, the logarithm of x to base ten is returned as before.

Example:

LOG(64, 2)

returns the number 6.
